...Color - Frequently Asked Questions

Interior Surfaces |
|
Can I stain the floor a different colour? |
| Yes, with Osmo Wood Wax Finish. Apply the product with a firm brush, allow it to work in for a few minutes and then wipe off the excess with a cloth, following the grain of the wood. Leave the floor to dry overnight, ensuring that there is good ventilation and then apply one or two thin coats of Polyx®-Oil to finish. |
|
What happens if I damage part of my floor? |
| Unlike many of the traditional lacquers, damaged areas on floors treated with our products can be sanded and re-treated with the same products without any visible brushmarks. |
|
Is there anything special to watch out for when treating hardwood floors? |
| Some hardwoods such as jatoba and merbau are dense and have a high oil content, which reduces their capacity to absorb other coatings. We recommend treating woods such as these with Wood Wax Finish Clear Extra Thin, which is thin enough to penetrate deeply into the pores of these wood species. |
|
What happens if I over apply the product by treating a floor? |
| If you have applied too much Polyx®-Oil, the drying time will be extended considerably. If this happens, provide additional ventilation by opening windows and doors so that the product can dry naturally by oxidation. If damage occurs to the surface as a result, repair the surface as described above. |
|
What happens if I under apply the product by treating a floor? |
| If you have applied too little of the product, the surface may watermark, the wood may dry out or appear dull. In such cases, please apply another thin coat of Osmo Polyx®-Oil. |

Exterior Surfaces |
|
Can I mix all the Osmo colour-shades among each other? |
| Yes. The colour shades of the respective product ranges mixable in any mixing ratio. The Osmo Country Colour 2404 (Fir Green) for instance can be mixed with the Osmo Country Colour 2703 (Charcoal) to darken the shade. Hint: Osmo Country Colours can be delivered upon request in 186 Mixed RAL-Classic shades. |
|
Which woodtypes to be used for exterior use should be protected long-lasting with Osmo WR wood impregnation? |
| By using an impregnation such as our WR wood impregnation the durability of woods such as spruce/fir, pine and Hemlock can be seriously increased. |
|
Can the Osmo WR impregnation be used without any additional finish? |
| No. The WR impregnation should not be used as a single coat only. To get full UV-protection and to keep the long-lasting beauty of the wood a final treatment (preferably pigmented for UV-protection) with Osmo Country Colour or One Coat Only is necessary. |
|
Why does fungal decay occur on exterior wood finishes and how can I remove it? |
| The most frequently appearing fungi show a punctual, brownish but mostly black affection. Moss and algae in contrast appear as a green film on the finish. These organisms discolor the wood and can spread all over the whole fagade. This affection is a result of high humidity and other environmental influences - particularly in umbrageous areas and near plants and water. The wood won't be destroyed by this discoloring fungus. The film can easily be removed by using our Osmo Gard Clean or by using a chloride dilution (5 % dilution; for household use. Can be purchased in drugstores e.g.). To prevent from such affections a finish containing fungicides or algicides is recommended (Osmo's Natural Oil Woodstain e.g.) |
|
Is a clear finish available that protects my facade from UV radiation? |
| Yes. UV Protection Oil (410/420). However, this only works with vertical surfaces such as cladding, roof overhangs, balcony elements, garden furniture, windows and doors. An actual UV-protection for exterior horizontal areas can only be achieved by using a pigmented finish. Therefore opaque colourshades offer a better UV-protection as transparent ones. Dark transparent shades perform better than light ones in this connection. |
|
Why does the colour in the tin look different than after it has been applied? |
| Depending on the woodtype they are applied on, finishes can appear in another colour shade. This shade does not have to match the small sticker on the colour tin. We recommend to apply a small sample treatment on a similar piece of wood if the desired result has been achieved. |
|
How should I treat a decking made of wood which are high in wood ingredients? |
| Exotic wood types (such as Iroko, Massaranduba, Teak, Bang-kirai e.g.) and especially wood types with a high resin content contain ingredients which make the wood durable and give resistance against fungus, blueness and insects. When the binding agents of our colours (natural oils) penetrate into the wood, these ingredients might avoid the penetrating and therefore decrease the drying time. Therefore we recommend to let the wood be weathered for approx. 2-3 months. A impregnation is not necessary due to the wood ingredients. Our special wood oils are designed for the colour-shades of the different wood types and to all their natural features and give them a refreshing, natural look and a smooth surface. By using a transparent finish for your wooden decking we recommend a final treatment of Osmo's Teak Oil (007) to protect the pigments from abrasion. Hint: For the treatment of bigger areas Osmo offers a special Flooring Brush (150 mm) which offers professional working conditions. |
|
Can I also spray-apply the Osmo Country Colour? |
| No. Osmo Country Colour should be applied thinly by brush or with our specially designed Roller and Brush Set on the clean wood surface. |
|
How should the wood surface be prepared before using Osmo Color? |
| The surface must be clean, dry (moisture content max. 20 %) and frost-free. |
